Lizard found by Florida biologist has the record body to poop ratio. The unpassed poop made up nearly 80% of the animal’s body weight. The lizard gulped down insects and other small reptiles near a pizza parlour in Cocoa Beach, Florida. It also swallowed particles of grease-soaked sand along with the food. Over the time the grains stuck together to form a lump that was too dense for the lizard to excrete.
As the lizard ate the bigger the poop mass grew. By the time the lizard was found by Natalie Claunch a doctoral candidate in the School of Natural Resources and Environment at the University of Florida in Gainesville it was slowly starving to death. There was no room to eat anything more. The poop was a dense ball in its gut. The lizard’s internal organs were lizard’s internal organs were so squeezed and damaged. The lizard weighed about 1 ounce (28 grams), and the mass alone weighed 0.8 ounces (22 grams). Northern curly-tailed lizards (Leiocephalus carinatus) are native to the Bahamas and other Caribbean islands; they were introduced in southeastern Florida in the 1940s, when a Palm Beach resident released several dozens of the lizards on his property to combat insect pests
Scientists previously documented a Burmese python (Python bivittatus), a species known for digesting enormous meals (and excreting huge poops), that produced a faecal mass representing a mere 13% of the snake’s body weight.
